Specification of Letters Patent.

Patented Nov. Y, 15511.

To all "whom it may concern:

Be it known that I, Oscar: KAvLn, a citizen of the United States, residing at Syracuse, in the county of Onondaga and State of New York, have invented a new and useful Improvement in 'lype-Writing lvlachincs, of which the following is a specification.

This invention relates to line or margin stop and locking mechanisms for typewriting machines, that is, to the mechanism for stopping the travel of the carriage at the ends of the line and locking operative parts of the machine, to prevent the printing of characters one over the other at the end of ti i The objects of the invention are to produce a desirable line stop and locking mechanism of simple and desirableconstruction which will positively stop the carriage ex actly at any desired pointin the line for which the margin stop is set, and lock the printing mechanism to prevent the printing of characters over each other at the end of the line, and which. is constructed to enable the ready release of the parts for printing additionalcharacters; also to provide the mechanism with a lock-releasing key or device in a convenient location which can be readily operated by hand to cnablethe printing of additional characters either after a preliminary or second action of the stop and lockm; mechanism also to arran c the 7 2:

parts to lock the universal bar which controls the carriage cscapementand the ribbon vibrator, whereby these devices well as the type-bars will be locked when thecarriage is arrested; also to so adapt the line stop and locking mechanism to a machine in which the platen is shifted into printing relation with'onc of two sets of type on the type-bars so that the action thereof will be the same regardless of whether the platen is in the normal or shifted position; also to improve line stop and locking mechanisms for typewriting machines in the respects hereinafter described and set forth in the claims.

In the accompanving drawings, consisting of three-sheets: Figure 1 is a central longitudinal sectional elevation of portions of a" front-strike typewriting machine embodying the invention, showing the normal'position the margin stops are adp stably secure...

l of the parts;

Fig. 2- is a transverse sectional elevation thereof in line 22, Fig. 1. Fig. 3 is a sectional plan thereof broken in places. Fig. 4 is a central longitudinal sectional elevation, on an enlarged scale, of the line stop and locking mechanism, showing the parts locked. Fig. 5 is a similar view showing the position of the parts when moved to release the carriage. Fig. 6 is a sectional elevation in line 6-6, Fig. t. Fig. 7. is a longitudinal sectional elevation of the line stop and locking mechanism in line 7-7, Fig. 2, looking in the direction of the arrow, Fig.

Fig. 8 is a view similar to Fig. 7, showing the position of the parts when the platen is shifted for printing upper case characters. Fig. 9 is a front sectional elevation, on an enlarged scale, of the lock lever and associated parts.

Like lettters of reference refer. to like parts in the several figures.

The invention is especially adapted for, and is described as applied to, a visible writing typewriting machine in which. the type strike the front side of the platen, and in which the platen is mounted on a pivoted shift frame for placing it'in printing relation to one or the othcr set of types on the type-bars, but the invention is also applicable to machines in which the platen is shifted by other means, and to non-shifting platen machines.

A. represents the main frame of the machine. u the top plate thereof; B the platen l. the platen carriage; D the shift frame on which the carriage is supported and travels laterally or transversely of the machine; E one of the type-bars which are suitably pivoted to strike the front side of the platen; ll' one of the key levers for operating the -l \'pc-bars; F the guide or vibrator ,for vibrating the ribbon to cover and uncover the printing point at. the type strokes; and G the rocking universal bar' which is rocked by the actuation of the key levers, controls the carriage csc'apemeut (not shown) andact-uates the ribbon vibrator. The top plate a is detachably secured by screws, or in any other usual manner, so that it can be detached from the frame 5. together with the parts mounted thereon. The carriage has a front bar 0 joining its ends upon which ath of the carria e sto and the o eratb 1 ing means therefor could be'dilfercntly constructed and arranged. I

N, Figs. 1, 2, 4 and 5, represents a lock lever which is located in the slot in the shift frame extension (1 in front of the abutment, and is pivoted at its upper end on a suitable pivot or screw it connecting the side walls of the shift frame extension. The lock lever preterably has trunnions or bosses, see

Fig. 9, which prevent lateral movement of vthe lever on its pivot, is normally held in the position shown in l lg. 1 by a suitable spring, such as the spring 71, Fig. $l,'surrounding the lever trunnions. and attached to the lever and to the shift frame extension.

The lower free end of the lock lever hangs, when swung forwardly to the position shown in Fig. 4, over a locking shoulder 72 on the front end of the operating lever for the ribbon vibrator, whereby this lever and the universal bar G, to which it is connected, are instantly locked against action. This prevents the operation of the carriage escapeinent connected to the universal bar and so stops the carriage, and as the universal bar holds its actuators from movement the type-bars cannot reach the platen, so that over-printing is prevented. The vibrator lever f, link f and lever f connecting it; to the universal liar constitute a sort of flexible connection between the lock lever and the type-bars which absorbs the force of the blows delivered by the type-bars without injury to any of the parts.

0 represents an operating bolt or device for the lock lever. This bolt or device consists, in the construction shown, of a screw which passes vertically through a hole in the abutment K and its rock shaft Z. aml having .a head or block 7 securely fuslcllctl to its upper end and provided with an A- shaped or oppositely beveled top. see Fig. (3. An arm q projecting rearwardly from the lock lever and having a slotted cnd engages under the head of the bolt. see Figs. 4- and 6, and in the normal position of the lock lever holds the bolt in position for its A-- shaped head to be engaged and the bolt dcpressed by the two studs 2" 9' depending from the carriage stop I. The upward movement of the bolt is limited by the engagement of the head at the lower end of its screw with the lower end of the abutment. The lever arm r preferably consists of a spring strip secured to the lever but it normally swings with the lever as a rigid part thereof. The only spring action of the arm 1 is to provide for any slight variation in the fitting'of the parts, and a rigid arm or intogral portion of the lever could be employed instead of the separate spring, if preferred.

In the operation of the machine, when the carriage approaclms nearly to the desired limit of its travel to the left, the first stud if onlhe carriage stop I will engage the A- shaped head of the lock bolt and depress the bolt, as shown in Figs. 4- and 6, thereby swinging the lower end of the lock l'ever over the locking shoulder 12 on the vibrating lever and locking the parts, as explained. The location of the stud Z is such that the carriage will come to a stop exactly at" the point for which the stop I is set. The locking action described is positive and instantaneous so that the carriage does not move a letter-space after the type-bars are locked. and this enables additional letters to be printed after the lock is released without necessitating adjustn'ient of the carriage. If it is desired to print one or more additional haracters after the parts have been thus temporarily locked, the push-rod M is pushed rcarwardly, thereby rocking the shaft ll andthrough it and the lever A and swinging the abutment rcarwardly. The l .(l( bolt 0 being mounted on the abutment will be? moved rcarwardly out.of'engagement with the stud or projection 2" ofthe carriagestop, whereiuion the spring n for the loclclevcr willthrow the lever end of the lever rearwardly out of engagement with the shoulder of the vibrated lever and ltllrP the lock bolt. The parts will then be freed and additional characters can be printed. "hen two characters have been printed the head of the bolt 0 will have passed the stud '1". and the push rod M bcing released, it will be moved forwardly by the spring on the rock shaft l1, and the abutment returned to its normal position by its spring m. The hcad of the lock'bolt will. then be in position between the studs or projections '1" on the carriage stop l, and characters can be printed until the secs ond stud engages and depresses the lock bolt in .the same manner is the first stud, thcrcby again locking the vibrator, carriage cscapcmcnt and type-bars from movement. .\t' the same time that the lock bolt is operated by the (Wxmtl stud I? the stop face of the carriage stop I will engage the abutment and positively arrest the carriage. The locking means can be again released and the carriage freed for printing still other characters, itthis is necessary, by again operating the push rod to move the bolt and abutment K clear of the stud 1 and face i respectively of the stop I.

The described mechanism thus provides for a preliminary and second stopping of the. tarriage and locking of the machine,

1,00%,Tlhti shift frame, while the push rod is mounted on the main frame and the parts that are locked together with the connecting means from the push rod are mounted on the top plate a, and each of these four groups is self-contained or complete in itself and can be mounted and adjusted on its supporting part before the supporting parts are assembled in the machine All of the differ ent groups assume their proper place when the machine is put together without requiring pins, linlrs or other connecting parts to be applied after the parts are assembled.

This is important in assembling. and also desirable when making repairs as it enables the carriage to be taken from the shift frame, or the shift frame from the top plate, or the top plate from the main frame without necessitating disconnection of parts of the stop and locking mechanism.
